# db-dump-xml v1.11 — Dump 1C configuration to XML files
# Source: https://github.com/Nikolay-Shirokov/cc-1c-skills
# NB: *nix-раскладку платформы (/opt/1cv8/<ver>/1cv8, без .exe) знает только .py-порт — PS на *nix не исполняется.

.SYNOPSIS
    Выгрузка конфигурации 1С в XML-файлы

.DESCRIPTION
    Выполняет выгрузку конфигурации 1С в файлы в четырёх режимах:
    - Full: полная выгрузка всей конфигурации
    - Changes: инкрементальная выгрузка изменённых объектов
    - Partial: выгрузка конкретных объектов из списка
    - UpdateInfo: обновление только ConfigDumpInfo.xml

.PARAMETER V8Path
    Путь к каталогу bin платформы или к 1cv8.exe

.PARAMETER InfoBasePath
    Путь к файловой информационной базе

.PARAMETER InfoBaseServer
    Сервер 1С (для серверной базы)

.PARAMETER InfoBaseRef
    Имя базы на сервере

.PARAMETER UserName
    Имя пользователя 1С

.PARAMETER Password
    Пароль пользователя

.PARAMETER ConfigDir
    Каталог для выгрузки конфигурации

.PARAMETER Mode
    Режим выгрузки: Full, Changes, Partial, UpdateInfo (по умолчанию Changes)

.PARAMETER Objects
    Имена объектов метаданных через запятую (для режима Partial)

.PARAMETER Extension
    Имя расширения для выгрузки

.PARAMETER AllExtensions
    Выгрузить все расширения

.PARAMETER Format
    Формат выгрузки: Hierarchical или Plain (по умолчанию Hierarchical)

.EXAMPLE
    .\db-dump-xml.ps1 -InfoBasePath "C:\Bases\MyDB" -ConfigDir "C:\src" -Mode Full

.EXAMPLE
    .\db-dump-xml.ps1 -InfoBasePath "C:\Bases\MyDB" -ConfigDir "C:\src" -Mode Partial -Objects "Справочник.Номенклатура,Документ.Заказ"
